Lymph node prognostic factors in head and neck squamous cell carcinomas.

Background: This retrospective study included 914 patients who underwent a lymph node dissection at our institute between 1980 and 1985. The primary tumor sites were oral cavity, 287; hypopharynx, 249; larynx, 247; and oropharynx, 131.

Patients And Methods: On the basis of anatomic considerations, the sentinel nodes for well-lateralized oral cavity tumors were defined as homolateral levels I, II, and III; for oropharyngeal, hypopharyngeal, and laryngeal tumors, the sentinel nodes were defined as levels II and III.

[Surgical and physical therapy treatment of benign paroxysmal positional vertigo].

Two treatments for the benign paroxysmal positional vertigo are presented and evaluated in this article. The first type of treatment is the surgical section of the posterior ampullary nerve according to Gacek and the second is physiotherapeutic by the manoeuvre of Semont. The section of the posterior ampullary nerve has been realised between 1980 and 1986 on 5 patients suffering from persistent and disabling positional vertigo.

Laryngeal pathologies observed in microlaryngoscopy.

A retrospective analysis of 738 consecutive microlaryngoscopic procedures, performed in 655 patients at the Geneva Clinic of Otolaryngology, Head and Neck Surgery between 1981 and 1987, was undertaken. The 4 most frequent laryngeal pathologies were polyps, hyperplastic chronic laryngitis, Reinke's edema and laryngeal cancer accounting for 76.6% of all encountered pathologies.
